While doing press for his action-thriller Bullet to the Head, which opened in theaters this weekend, actor Adewale Akinnuoye-Agbaje also discussed his duel role as Algrim the Strong and Kurse in the upcoming superhero sequel Thor: The Dark World. Algrim is one of the Dark Elves that are lead by Christopher Eccleston's Malekith the Accursed, who is seeking vengeance for an ancient grudge. After being double-crossed by Malekith and thrown into a pit of lava, he manages to survive, transforming himself into the creature Kurse. Here's what the actor had to say about the challenges in pulling off this dual role.

"It's an amalgamation of a bull and a lava-like creature. He has very animalistic tendencies but with this insatiable and unstoppable power. As an actor, that's one of the hardest things to embody. You have to realize you are probably the most powerful thing you could imagine. And you have to be that. You can't pretend, so that when you face Thor, it's real."

He also spoke about the bulky costume he had to wear on the set, which weighed 40 pounds.

"The outfit weighed about 40 pounds. I'm sure there will be a certain amount of CGI but a good 80% was me in that suit. The outfit informed how I was going to move - the horns - his fighting style as well. It's almost like he's made out of stone."
